Three independent experiments were performed in each assay. *P<0.05, and **P<0.01 TNF-α, tumor necrosis factor-α; ULK1, uncoordinated 51-like kinase 1; ALG5, asparagine-linked glycosylation 5; COL2A1, type II collagen; ACAN, aggrecan; MMP-13, matrix metallo protease 13; ADAMTS-5, a disintegrin and metalloproteinase with thrombospondin motifs-5; SIRT1, sirtuin type 1.

Article Snippet: Total 50 µg protein sample (per lane) was separated on SDS-PAGE gel, blotted onto PVDF membranes, and blocked in 5% non-fat milk for 1 h. The membranes were probed with mouse polyclonal antibodies to ULK1 (120 kDa; 1;1,000; ab128859; Abcam, Cambridge, UK), ALG5 (32 kDa; 1;1,000; ab108327; Abcam), Beclin-1 (52 kDa; 1;1,000; ab62557; Abcam), LC3II/LC3I (LC3-II, 17 kDa, LC3-II 19 kDa; 1;1,000; ab48394; Abcam), COL2A1 (142 kDa; 1;1,000; ab34712; Abcam), ACAN (250 kDa; 1;1,000; ab36861; Abcam), MMP-13 (54 kDa; 1;1,000; ab39012; Abcam), ADAMTS-5 (73 kDa; 1;1,000; ab41037; Abcam), SIRT1 (120 kDa; 1;1,000; ab110304; Abcam), phospho-PI3K (p-PI3K) (84 kDa; 1;1,000; ab182651; Abcam), PI3K (123 kDa; 1;1,000; ab151549; Abcam), p-AKT (65 kDa; 1;1,000; SAB4301414; Sigma-Aldrich; Merck KGaA), AKT (55 kDa; 1;1,000; SAB4500797; Sigma-Aldrich; Merck KGaA), p-mTOR (250 kDa; 1;1,000; ab137133; Abcam), mTOR (252 kDa; 1;2,000; ab2732; Abcam), and GAPDH (36 kDa; 1;2,000; ab8245; Abcam) overnight at 4°C, respectively.
